SLIDING DOOR.

Application filed August 16, 1916.

[0 all whom, it may concern:

Be it known that I, Anruun A. Ilnmun', a citizen of the United States, residing at Chippewa Falls, in the county of Chippewa and State of Wisconsin, have invented new and useful Improvements in Sliding Doors, of which the following is a specification.

This invention relates to in'iprovements in grain car doors, the object of the invention being to provide a sliding grain car door of improved construction, which is extremely strong and durable and which can be readily moved to either open or closed position.

The invention consists in the features of construction. combination, and arrangement of devices, hereina't'ter fully described and claimed.

in the accompanying drawings:

Figure 1 is an elevation, showing the in nor side ot. a grain car door constructed and arranged in accordance with my invention and in open position, the floor of the car being indicated in section.

Fig. 2 is a similar view of the same and with the door in closed position.

Fig. 3 is a vertical sectional View oi the same.

Fig. 4: is a detail elevation of the door and showing the inner side thereof.

The floor of a box car is indicated at 1, one of the walls at 2. and a door way at 4.

The sliding door 7 is in accordance with my invention, composed oi. a series of scctions 8 which are slidably related to one another and are avenged one above the other as shown and are adapted to be moved to open or closed position independently of one another. The door sections are arranged to operate on the inner side of the wall 2 and are mounted for sliding movement between the studs of the wall and suitable stanchion bars 9. The stanchion bars are preferably constructed of iron or steel but may be made of any suitable material and have their lower ends out-turned as at 10 and secured on the floor by means of screws, the upper ends of the stanchion bars being secured as at 11 to the plate 12 of the car and to a horizon tally arranged bar 13 under the plate. The stanchion bars are provided on their outer sides near their opposing edges with outturned keeper lugs 14. A casing 15 is provided which is composed of sections of sheet metal of appropriate size and thickness, the sections of the casing being secured as shown between the stanchion bars and their lugs Specification of Letters Patent.

14 and serving to cover and incase the inner side oi the door and to form a housing therefor, when the door is in open position in connection with the stanchion bars as will be understood.

The bottom section of the door has its lower edge shod with channel iron as at 16 and arranged to operate in a channel rail 17, and at its inner end and lower corner, the said lower door section is rabbeted as at 18, so that when the lower door section is moved to closed position across the door way 4, said rabbet 18, permits said lower door section to drop a. slight distance from the channel rail 1T and thereby cause the lower edge of said door section to bear snugly on the car floor or door sill.

Each door section is provided at points near its ends and at its center with countersunk reinforcing metallic bars or straps 19. The door sections may be made of any suitable kind of wood or other suitable material. The uppermost. door section 8 is provided with a cap 20 on its upper side. Each door section excepting the uppermost has its upper edge beveled on opposite sides and provided with a. correspondingly cross sectional shaped metallic wear strip 22. Each door section excepting the lowermost. has its lower edge correspondingly grooved as at 23 and provided with a correspondingly shaped metallic shoe or strip 24:. Hence each door section excepting the uppermost presents upwardly converging planes at its upper edge so that grains and other particles are prevented from lodging on the upper edges of the door sections.

Track rails to guide and slidably support the door sections are also provided and are shown at These track rails may be made of iron, steel, or other suitable material and are shaped cross sectionally to correspond with the beveled and grooved upper and lower edges of the door members between which said track rails are arranged and said track rails are also provided with downwardly extending vertical webs 26 on their outer sides, which are secured to certain of the studs, said guide and track rails being also provided at their inner sides with upturned vertical webs 9.7 which bear against the inner sides of the door sections and are arranged in rabbets 29 with which the door sections are provided.

It will be noted that the guide and track rails 25 support all the door sections except- 30 in their lower edges at their inner ends or lower inner corners, which rabbets, when said door sections are in closed position permit said sections to drop slightly so that the sections when in closed position bear snugly one upon the other and prevent cracks from existing between them.

I The guide and supporting rails 25 are provided at suitable points with openings through which grains or other particles or substances may drop in the event that grains or other substances or particles should get between the door sections. Each door secti on is provided at its front end with a staple Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents. 7

shaped handle 32 to enable the door section to be readily moved to either open or closed position. A look and sealing device is provided for each door section to lock the same in closed position and a locking mechanism is also provided for each door section to secure the same when in fully opened position.

Having described the invention, What is claimed is:

In combination with a sliding door co1nprising superposed slidably related sections, fixed supporting tracks for the several sections, and arranged between said sections, said tracks being of inverted V-shape cross sectionally and the opposing edges of the door sections being shaped to correspond with the tracks.

In testimony whereof I afiix my signature.
